TO ALL WHOM IT MAY CONCERN:

Beit known that I, ALBERT C. BROWN, of Chicago, in the county of Cook, and State of Illinois, have invented a new `and useful Improvement in Weather-Strips; and I do hereby declare and make known that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and the letters andfigures marked thereon, which form part of this specification.

My invention relates lto an improvement in the construction of rubber moulding to be used and applied upon doors Aand windows for the purpose of excluding cold, wind, dust, snow, and rain; and it consists in forming the rubber bearing-surface by folding the rubber strip, and inserting the edges of the same securely in suitable grooves in the moulding, thus presenting a rounded, firm, elastic bead for the bearing-surface against the door or window, and in combining, with the said rubber moulding, a concave stop or abutment to be applied upon .the door or sash, so as to receive said elastic bead, and form a continuous contact between the rubber and its receiving-groove, instead of having simply a lineof contact, as in the ordinary mode of applying weatherstrips, thus much more perfectly attaining the object desired.

To enable those skilled in the art to manufacture and use my said invention, I-will proceed to describe the same with particularity, making reference in so doing to the aforesaid drawings, in which- Figure 1 represents a front view of my invention as applied to a door.

Figure 2 is atransverse section at the line a; in-Vg. 1, and

Figure 3 is a cross-section ofthe threshold and its attachment.

Similar letters of reference in the several figures denote the same parts'of my invention.

In applying my invention, the rubber moulding is applied or fastened to the stop`or casing of the door or window, and the concave bed receiving the elastic bead is applied upon the door or the sash. When applied upon thebottom of doors, however, the moulding is made much heavier and is applied upon the door, while the ,concave groovcd bed is secured upon the threshold, as clearly seen in the drawings.

- A represents a. door, and B the casing o r stop, against which the margin of the door closes when shut. Upon the sides of thestop or easing, the moulding b is secured in such a manner that the rubber bead a, inserted therein, projects beyond'the face. of the stop, so that the bed O upon the door shall press against the bead when the door is\closed, thus making a close joint all around the door, as clearly shown in fig. 2.

C represents a strip or" wood extending around the door' in such a position that the bead a of the moulding fits into the concave channel e, formed in the strip O, as clearly shown in the drawings, thus forming a tight joint, not at a singlelinearound the door, but for thc whole concave surface of the stop and convex surface of the bead. l

It is obvious that sueli ajoint as is produced by my invention will be far more eifectualv in excluding cold and dust and storms than the ordinary kind of weather-strips, where the'contaet between the'vmoulding or rubber and the door is a line without width. i Y

The rubber at the bottom of the door closes against the concave groove c inthe strip C upon the door-sill T, producing the same result. i

Having described the construction and operation ofmy invention, I will specify what I claim, and desire i to secure by Letters Patent.

I claim thc combination of the moulding'a bwith the stop C, provided with a groove, c, arranged substantially as and for the purposes specified. p

I ALBERT C. BROWN.
